# Sight Sciences reports MACs delay effective date of LCDs impacting OMNI and SION to January 29, 2024

## Summary
- Five MACs delayed effective date of local coverage determinations on Micro-Invasive Glaucoma Surgery from Dec 24, 2023 to Jan 29, 2024.
- LCDs identify certain procedures as investigational, including canaloplasty with trabeculotomy ab interno associated with OMNI Surgical System.
- The states served by these five MACs accounted for approximately 63% of Sight Sciences' Surgical Glaucoma revenue in 2022.
- Sight Sciences strongly disagrees with LCDs' characterization and is pursuing remediation, including engagement with MACs and CMS, and potential reconsideration request.
- The company is still assessing potential impact on coverage for its SION Surgical Instrument technology.
